The Chiefs torched a very good New England defense for 38 points last week and also put up 40 in the opener at Cleveland.
"We'll have our hands full this week," said linebacker Zach Thomas. "They're going to have yardage. You look at the way they played Cleveland and New England and gashed them.
"Hopefully, our offense comes through because they're going to have some runs against us. Their offensive line is the best in the league. We definitely need our offense to step up, like they have in the first three games. We have to step up ourselves. We can't get rattled or give up the big play."
The Chiefs offense features one of the top running backs in the league in Priest Holmes and the best tight end in Tony Gonzalez, in addition to an offensive line that includes perennial Pro Bowl selections William Roaf and Will Shields.
"Their whole offensive line is good," said defensive end Jason Taylor. "It's best offensive line we've faced so far this year, and it might be the best we'll see all year. It's a good bunch. They're big, physical guys and they'll try to maul you. We expect a slug fest out of them."
One problem for the Chiefs offense, both this year and last season, has been quarterback Trent Green's nasty habit of throwing untimely interceptions.
"Right now what we have to do with Trent is eliminate the one bad play," said Chiefs coach Dick Vermeil. "It's his own competitive nature to feel he has to make the play."
Green has thrown five interceptions in three games this season and has been sacked four times. But the key to stopping the Chiefs offense is shutting down Holmes, who already has seven touchdowns and leads the team in receiving.
"He's outstanding," Taylor said. "He's an all-around back. He does pretty much everything. He's been impressive on tape. He's got a build like Marshall (Faulk) and he does things similar to Marshall. Priest is right up there with him."
